To all whom it may concern.-

Be it known that I, FREDRICK MAoFAR- LAND, residing at Meriden, in the county of Jefferson and State of Kansas, have invented a new and Improved Exterminator, of which the following is a specification.

My invention seeks to provide a very simple, inexpensive, and easily-manipulated appliance especially adapted for the extermina tion of prairie-dogs, gophers, rats, and other animals orrodents that burrow underthe earth and which is also capable of being effectively used for destroying microbes and germs that generate in sewers; and in its generic nature my invention comprehends a portable body formed of an upper and a lower section hav ing means for quickly and effectively joining them together, said sections having a cooperative arrangement whereby the lower will serve as a fire-box, the upper as a gas-collector, the upper section havinga specially-proj ected nozzle or offtake and the lower a blower attachment.

In its more specific nature my invention consists in certain novel details of construction and peculiar combination of parts, all of which will hereinafter be fully explained, and pointed out in the claims, reference being had to theaccompanying drawings,in which- Figure l is a perspective View illustrating my invention set up for use. Fig. 2 is a vertical section of the same. Fig.3 is a horizon'ral section, and Fig. 4 is a view illustrating the two-part casing or holder separated. Fig. 5 is a detail View hereinafter referred to. Fig. 6 is a side elevation, parts being in section, illustrating myinvention as mounted on a wheelbarrow or portable support. Fig. '7 is a plan view of the construction shown in Fig. 6.

In its practical construction my invention embodies a holder or casing of suitable form, preferably egg shape, and comprises a lower section A, of cast metal, and an upper section B, of sheet metal. The two members A and B have opposing ho rizontalflanges (designated by a and b) adapted to snugly seat against each other, and to provide for securely holding the upper member upon the lower and also for conveniently detaching the same when desired the flange a onthe lower section A has turned lips a and the upper flange b has notches 1), whereby the said flange b can be quickly seated on the flange 0., and by a slight turn of member B the two flanges will be interlocked. The lower section A isalso provided with haudies 0 O, disposed at diametrically opposite sides, pivotally hung, and each of said handles has a projection c 0, adapted tocooperate with the two flanges a and b when they r (the handles) are swung up to a horizontal plane during carrying the apparatus from place to place, such arrangement of parts providing for positively holding the two parts A B from becoming disconnected in handling. The section A in practice is cast with legs a and at its bottom it has a nipple a the outer end of which is suitably formed to detachably hold the discharge-nozzle d of a blower or bellows D. The upper sheet memberB has an opening b cut from the bottom or flange part upward and provided with a hinged door b and at the upper or dome end the member B has an ofltake b, that terminates in a tapered and 'elongated nozzle b the outer end of which is bulbed to receive a hose E when it is desired to eject the fumes from the gas-generating body at some dis-- tance therefrom.

To facilitate theuse of the apparatus, the offtake 11 preferably has a swiveled and an air-tight'joint with the dome portion of part B, so it can be turned to the directions desired and to hold the ofitake to different adjustments. The connection thereof with the domedike body includes means in the nature of opposing corrugated surfaces, the joining of which is made sufficiently snug that the spring of the metal will tend to hold the 0dtake-clamp to the different positions-to which it may be set, as clearly shown in Fig. 5.

The dome or member B may be provided with additional outlets in its'upper end (see, for example, 19 and which when no connected with the hose or pipe connection are closed by screw-caps 6 as shown.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the advantages ofmy invention will be readily apparent. In the use thereof the fumigating or germicidal chemicals are deposited within the generator or body A B upon a fire-surface of wood or other combustible material, the fire being quickly started and maintained by the bellows D. The fumes generated collect in the dome of the member 13 and pass out into the oiftake pipe or nozzle, from which they are ejected at any distance from the generator-body A B by proper manipulation of the hose when it is used or the ofiftake member when it is desired to eject the fumes into walls, crevices, beds, the.

I am aware that exterminators comprising a hollow receptacle having a fire-pot and a collecting-chamber have heretofore been provided; but my invention, so far as I know, diiferentiates from what has heretofore been provided in this art in the peculiar and novel correlation of the several parts, particularly the means for detachably joining and interlocking the flanges of the two parts A and B, the cooperating adjustable offtake, and the combined arrangement of the entire construction.

The apparatus is very simple, cheap, and durable and in practice is provided to be very well adapted for the purposes for which it is intended.

In Figs. 6 and 7 I have illustrated my apparatus as mounted upon a portable support, such as a wheelbarrow, and when thus supported the bellows D is secured to the under side of the barrel-board f and the said bellows is operated by a lever D mounted upon a cross-bar d, rockably supported on the frame of the wheel-barrow F.

Having thus described my invention, what I claim, and desire to secure by Letters Pat cut, is-

1. The combination with a member A, having a blow-opening at the lower end, and a horizontal flange at theupper end; of the top member B, having adome portion and a horizontal flange for opposing the other flange, the two flanges having means for interlockin g when turned relatively to each other, the

top member B having a feed-inlet 12 provided with a door 11 the upper member having an offtake in the dome portion,all being arranged substantially as shown and for the purposes described.

2. The combination with the bottom member A, having an air-inlet at the lower end, and a horizontal flange (1, at the upper end, having inturned lips, the member B, having a flange b to seat in the flange a, said flange Z), having notched portions, the said mem her having an offtake in its upper end, and a door-equipped feed-opening, and the handles *pivotallyhung on the member A, said handles having projections adapted to interlock with the flanges of the two members A and B, when turned to a horizontal plane, substantially as shown and for the purposes de scribed.

ment in fumigating and disinfecting appliances of the character stated, comprising a receptacle consisting of a bottom section A, having an air-inlet at the lower end, provided with a nipple for attaching ablower, and having a horizontal flange, provided with inturned fingers, and pivotally-hung handle members having extensions for closing over the said flange, when turned to a horizontal position, the sheet-metal top 13 having a dome top, provided with a discharge, a nozzle adjustably connected to said discharge, said member B also having a horizontal flange 1), adapted to seat upon the flange a, and having notches for interlocking with the lips of the said flange a, all being arranged substantially as shown and for the purposes de scribed.
